Features of fertilization characteristic of angiospersms: 1) development of male and female plant parts – called gametophytes 2) pollination 3) double fertilization c. Characteristics of angiosperms that make them successful: they have flowers that attract pollinators and they use endosperm in the seed to store food. 3a. Vegetative reproduction: plant offspring is identical to itself. By Mitosis. 3b. Sexual Reproduction – advantages are new combinations of genetic traits help the organisms survive changing environmental conditions. Disadvantage is that it takes time and resources to produce offspring. Asexual reproduction advantage is rapid growth when there is a favorable environment. But there are no new combinations of traits. Day 4: Wednesday 12/3 Mrs. Bryan What Did I Miss?

Zebrina Lab • Q of T D #2: In a flowering plant, how does the sperm reach the egg? What are the sperm contained in? What are the egg contained in? • Answer. The sperm reaches the egg through a pollen tubs. Sperm are contained in a pollen grain and the egg is in the ovule. • Homework: . READ 11.4 pp. 323-329 (Meiosis) • Do AQs #1-5 p. 329 • Copy figures 11.5 and 11.6 on pp. 324-325 Homework Answers: Day 5: Friday 12/5 Mrs. Bryan What Did I Miss? Biology Handouts: Inv. 17 Mitosis v. Meiosis (paper clips) Agenda: • 1. Observe Planaria and Zebrina 2. Lecture: Meiosis and videos Q of T D #3: What is cross pollination? What is self pollination? How would a horticulturist make sure a plant crosspollinates instead of self-pollinates? • Answer. Cross pollinating is when the pollen from one flower pollinates a different flower on a different plant. • Self pollination is when the pollen from a flower pollinates a flower on the same plant. • A horticulturist can prevent self pollination by removing developing stamens on one set of plants and removing developing pistils/carpels on another set of plants. Homework: • Finish Biosphere Report Finish Inv. 17. You may use online resources (posted to my website) Meiosis Quiz on Thursday Homework Answers p. 329 #1-5 1a. . Main results of Meiosis - 4 haploid cells that are genetically different from each other and different from the original cell. 1b. sperm and egg cell each contain 23 chromosomes 2a. Draw a diagram of meiosis and describe each phase. See p. 326. And handout. Prophase 1 – formation tetrads, crossing over. Metaphase 1 – independent assortment. 2b. Shoes are pairs in a closet, like chromsomes are paired in a diploid cell. A “haploid” shoe collection would have only one shoe of each kind. 3a. Mitosis: produces 2 genetically identical diploid cells Meiosis produces four genetically different haploid cells. 4a. Principle of independent assortment: chromosomes assort independently. 4b. If the genes usually assort independently they are far from each other. . Day 6: Tuesday 12/9 Mrs. Bryan What Did I Miss? Biology Handouts: stop motion videos Agenda: 1.

Answer. 1) • Sepals • Petals • stamens • pistils 2) A pair of chromosomes that are similar and contain the same kind of genes. • Homework: Study for exam. Check Aeries and make sure all work is complete. Due by Monday. . Homework Answers: p. 826 1a. Asexual reproduction results in less genetic diversity than asexual reproduction. 1b. Sexually reproducing populations are better able to adapt to changing conditions. 2a. Internal fertilization – eggs are fertilized inside the body of the egg producing individual. External fertilization – eggs are fertilized outside the body. 2b. a nymph is a stage of development of an animal that undergoes incomplete metamorphosis. It resemebles an adult but lacks functional sexual organs. A pupa is the stage of development of an animal that undergoes complete metamorphosis in which a larva develops into an adult.
